Abstract
A method for recovering disc management information of a recording medium. (a) When the recording medium is not closed, a readable TDMS which is included in an in-use TDMA of TDMAs of the recording medium and is readable is searched for. (b) It is determined whether a piece of information associated with an inconsistency flag of the readable TDMS is reliable. (c) If the associated piece of information is unreliable, at least a detection condition is determined according to the information included in the readable TDMS and the in-use TDMA. (d) A detection procedure, constrained by the at least the detection condition, is performed on the recording medium for determining an update on the piece of information associated with the inconsistency flag. (e) An update TDMS is generated according to the readable TDMS and the update on the piece of information associated with the inconsistency flag.
